In addition to their aesthetic appeal, steel wall claddings provide functional benefits with respect to weather resistance, durability and non-combustibility.

This publication provides guidance on “single skin” steel wall cladding products on good practices relating to weathertightness, moisture management and structural support with reference to NCC requirements for non cyclonic areas.

Correct detailing and installation of flashings and membranes is key to weatherproofing a wall cladding system and common installation details, including recommendations for minimum flashing covers are provided.

There is also a section on Insulated Sandwich Panels with guidance relating to the design, storage, handling and weatherproofing compliance with NCC2022.
